REENFORCED ROAD CONSTRUCTION.

Application filed May 28, 1921. Serial No. 471,583.

Constructions, of which the following is a Figure is a detailed perspective view full, clear, and exact specification. of one of the wedge-shaped key members of 60 This invention relates to pavement or said pavement.

To further lock or connect the surface members 8 to the foundation members 1 and 2, tie bolts 13 may be employed, the lower end of each of said bolts being embedded in said foundation members, while their upper ends are embedded in said surface member, as best shown in Figures 2 and a. It will be understood that the pavement may be made of any width desired and will in practice he made much wider in proportion to its other dimensions than indicated by the accompanying drawings.

In place of the cast metal supporting n'iembers 8, shown in Figures 1, 3 and 8, sheet metal members 14-, Figure 4:, may be used. The ribs 15 on said members 14:, corresponding to the ribs 9 on the members 8, may be formed by bending the middle portion of said members 14 into the form of inwardly extending beads, as shown in Figure 4. Said'beads 9 and 15 may be omitted, if desired, and the surface members 10 formed with smooth inclined lateral faces 16, as shown in Figures 6 and 7, the incline of said faces serving to support said surface members and the bolts 13 serving to anchor them to the foundation members. The ends of the surface members 10 may be stepped, if desired, to prevent the upper edge thereof from chipping off, said stepped formation being indicated. at 17 in Figure 9.

Referring now to Figures 10 to 15 of the drawings, the foundation 20 for the pavement may be made continuous and with a succession of arches 21, said foundation being preferably supported on cross pieces 22 arranged between the arches. Said foundation 20 has a continuous groove or recess 23 formed in its upper surface to receive paving blocks 24 arranged in transverse rows, as best illustrated in Figure 12. Between each transverse row of the paving blocks 24, spacing members 25 are preferably arranged, the latter terminating slightly below the surface of the former. The blocks 24 may be made of concrete, wood, or any other suitable material, and the spacing members 25 may be made of metal or other durable substance.

Each spacing or separating member 25 has perforations 26 therein for the passage of screws 27, Figure 10, which serve to fasten said member to the paving blocks of the adjacent transverse row. The heads 28 of the screws 27 project beyond said spacing member and engage sockets 29 formed in the blocks 24 of the row at the other side of said member 25. At intervals along the foundation 21, wedge-shaped key members 30 are inserted between adjacent rowsof paving blocks 24 instead of spacing members 25. IVl1en said key members are removed, the paving blocks may be readily adjusted with their sockets 29 engaging the heads 28 of the screws 27, and when said bers key members are put in place, they hold said blocks and spacing members compactly together so that the heads of the screws interlock with the notches 29.

The key members 30 preferably extend through the sides of the foundation 20 in which corresponding notches 31 are formed, as shown in Figure 10. To retain said key members in position longitudinal rails 32 are embedded in notches 33 in said key members, said rails also fitting in corresponding notches 3a in the end paving blocks of each row and in similar notches 35 in the spacing members 25. The rails 32 may be fastened in any suitable manner, as by screws 36, Figure 12, arranged at intervals along the same and engaging into certain of the paving blocks which are held together by the screws 27 as already explained.

I claim:
